Object abbreviations used in this document

We described how your new GRE scanner utilizes an Object Oriented User
Interface in the Introduction and Overview sections of this manual. You
learned that the key components of this new user interface are the Scan-
nable Objects, which are, of course, "things that can be scanned". As you
begin to use your new scanner, you will notice that the object names are ab-
breviated so that they can easily fit into the 16 character LCD. (Imagine what
the radio's display would look like if "Trunking Talkgroup Object" was spelled
out in its entirety every time it was necessary to show it in the display.)
You should take a moment and become familiar with these abbreviations
now. For consistency, the same abbreviations for the different object types
are used in the radio and here in the manual.
TGRP
TGRP is used to represent a Trunking Talkgroup Object. Trunking Talk-
groups are "virtual" channels that exist on a trunked radio system. A trunked
radio system is a radio system where a small group of radio channels are
automatically shared between a larger number of users and user groups.
This sharing of channels is managed automatically by a special computer,
called a controller, or by other specialized hardware. For now, all you need
to know is this; if you want to monitor a talkgroup on a trunked radio system,
you must store that talkgroup's parameters in a TGRP object.
TSYS
TSYS is used to represent a Trunking System Object. A TSYS is a special
object type that is used when creating TGRP objects. A trunking talkgroup
must be associated with a specific trunked radio system in order for it to op-
erate. There are parameters that are associated with trunking systems, such
as the type of trunked radio system technology used, the frequencies that
the system uses to broadcast control data, etc. Instead of entering these
parameters over and over again every time you create a new TGRP on the
same trunked radio system, you create a TSYS object with all of the system
parameters, then specify that TSYS object for each TGRP you create on the
same trunked radio system. A TSYS cannot be scanned by itself and is not
considered a Scannable Object. It is a "configuration object" that can be
used over and over again when adding talkgroups for a specified trunked
radio system.
CONV
CONV is used to represent a Conventional Channel Object. A Conventional
Channel Object is a regular, non-trunked frequency used for radio communi-
cations. CONV objects are used to store the parameters for any radio chan-
nel that is not a part of a trunked system. For example, if you want to moni-
